But here's what I did. I used the stock 20B injectors, 3 in the block, and 3 at the far end of the runners. For the 3 in the block, which are the primaries, I used the stock 20B fuel rail and cut off the slip fittings and the pressure regulator and welded AN fittings onto each end. Problem half solved. For the secondary injectors which are located out near the runner bellmouths, I fabbed a fuel rail out of 1" square 4130 tubing and welded AN fittings onto each end. I then added small pieces of round 4130 tubing for the injectors to slip into. Everything was tig welded and probably lighter than the aluminum extrusion fuel rail. If you follow this method, be sure to use thick enough round tube to allow for a taper on the inlet. The taper makes it easier to insert the injector & o-ring into the bore without cutting the o-ring. I used a Moroso fuel pressure regulator (MAP referenced) which I mounted on the firewall. Mark S.

Marv and Steve,
The 20B injectors are pretty m= uch the same as the 13B in all the later models. Check the www.SDSEFI.com site, as Ross the p= ropriotor has either made or is representing a aluminum body piece that wil= l hold the injector. Most of the injectors are 10mm IIRC. The body of the i= njector has an o-ring on it to seal in the bore, and there is a groove on m= ine that are held in by a fork that is held down by a 6 x 1.0 screw. The 20= B has large ports like the rare 13B Cosmo engine and there is a primary inj= ector in the larger of the 2 ports, on mine at least.
